Abstract

A distribution server restructures content and information published to a topic tree for more efficient and meaningful presentation to a subscribing client. To do so, the distribution server receives a request to create a topic view from a client and creates the topic view in response. The topic view includes a set of selected topics and a topic view mapping. The topic view mapping maps the topic paths for the set of selected topics to a set of reference topics at a set of reference paths. In other words, the topic view restructures the content and information by creating new branches in the topic tree. Whenever a selected topic receives an update from a publisher, the distribution server publishes the update as restructured content and information to the reference topics at the reference paths. A client subscribed to the reference path receives the update in a restructured manner.

Claims21

Dependent claims

A method for restructuring content published to a topic tree by a plurality of publishers, the topic tree comprising a plurality of topics, with each topic of the plurality of topics corresponding to a respective topic path of a plurality of topic paths to which clients can subscribe, the method comprising:

receiving a topic view creation request from a client, the topic view creation request specifying a requested mapping of a set of selected topics in the topic tree to a set of reference topics in the topic tree according to a syntax of the topic view creation request;
responsive to receiving the topic view creation request, creating a set of reference topic paths in the topic tree based on the syntax of the topic view creation request, wherein each reference topic path in the set of reference topic paths comprises a reference topic of the set of reference topics corresponding to a selected topic of the set of selected topics as specified in the requested mapping;
receiving, from a publisher of the plurality of publishers, a topic update defining topic values for at least one of the set of selected topics;
responsive to receiving the topic update, restructuring the topic values by mapping them from the set of selected topics to the set of reference topics;
and
publishing the restructured topic values from the topic update to a client subscribed to a reference topic of the set of reference topics.

3 more elements

A non-transitory computer-readable storage medium storing computer instructions for restructuring content published to a topic tree by a plurality of publishers, the topic tree comprising a plurality of topics, with each topic of the plurality of topics corresponding to a respective topic path of a plurality of topic paths to which clients can subscribe, and the computer instructions, when executed by one or more processors, causing the processors to:

receive a topic view creation request from a client, the topic view creation request specifying a requested mapping of a set of selected topics in the topic tree to a set of reference topics in the topic tree according to a syntax of the topic view creation request;
responsive to receiving the topic view creation request, create a set of reference topic paths in the topic tree based on the syntax of the topic view creation request, wherein each reference topic path in the set of reference topic paths comprises a reference topic of the set of reference topics corresponding to a selected topic of the set of selected topics as specified in the requested mapping;
receive, from a publisher of the plurality of publishers, a topic update defining topic values for at least one of the set of selected topics;
responsive to receiving the topic update, restructure the topic values by mapping them from the set of selected topics to the set of reference topics;
and
publish the restructured topic values from the topic update to a client subscribed to a reference topic of the set of reference topics.

A system for restructuring content published to a topic tree by a plurality of publishers, the topic tree comprising a plurality of topics, with each topic of the plurality of topics corresponding to a respective topic path of a plurality of topic paths to which clients can subscribe, the system comprising:

one or more computer processors;
and
a non-transitory computer-readable storage medium storing computer program instructions, the computer program instructions executable by the one or more computer processors to perform operations comprising:
receiving a topic view creation request from a client, the topic view creation request specifying a requested mapping of a set of selected topics in the topic tree to a set of reference topics in the topic tree according to a syntax of the topic view creation request;
responsive to receiving the topic view creation request, creating a set of reference topic paths in the topic tree based on the syntax of the topic view creation request, wherein each reference topic path in the set of reference topic paths comprises a reference topic of the set of reference topics corresponding to a selected topic of the set of selected topics as specified in the requested mapping;
receiving, from a publisher of the plurality of publishers, a topic update defining topic values for at least one of the set of selected topics;
responsive to receiving the topic update, restructuring the topic values by mapping them from the set of selected topics to the set of reference topics;
and
publishing the restructured topic values from the topic update to a client subscribed to a reference topic of the set of reference topics.
